"I must pass into light. I must breathe the air of the sky, or I shall perish in this vault," he muttered in a hoarse voice, which the fitful echoes mocked by throwing his words as it were, to each other, even to the faintest whisper of its last recipient.
Gradually and painfully he commenced his meditated retreat.
Tristan's brain still whirled with the emotion that had so entirely overwhelmed his mind, as, staggering through the interminable gloom, he set forth on his toilsome, perilous journey.
Suddenly however he paused, bewildered, in the darkness. He had no doubt mistaken the direction, and a gleam of light, streaming through the fissure of the rock, informed him that there were others in this abode of darkness, beside himself.
Had he come upon the object of his quest?
For a moment Tristan's heart stood still, then, with all the caution which the darkness, the danger of secret pitfalls and the risk of discovery suggested, he crept toward the crevice until the glow gradually increased. From the bowels of the earth, as it were, voices were now audible; they seemed to issue from the depths of a cavern directly below where Tristan stood. Groping his way carefully along the wall of rock, he at last reached the spot whence the light issued and presently started at finding himself before an aperture just wide enough to admit the body of a single man. A sort of perpendicular ladder was formed in the wall of narrow juttings of stone, and below these was the rock chamber from which the voices proceeded.
It was some time ere the confusion of his ideas and the darkness allowed Tristan to form any notion of the character of the locality, when it suddenly dawned upon him that he had strayed into a place regarding which he had heard and wondered much: the Catacombs of St. Calixtus.
This revelation was by no means reassuring, although the presence of others held out hope that he would discover an exit from this shadowy labyrinth.
For a moment Tristan remained as one transfixed, as he gazed from his lofty pinnacle into the shadowy vault below.
He saw a stone table, lighted with a single taper, in the centre of which lay an unsheathed dagger, and an object the exact character of which he could not determine in the half gloom, also a brazen bowl. About a dozen men in cloaks with black vizors stood around, and one, taller than the rest, the gleam of whose eyes shone through the slits of his mask, appeared to be concluding an address to his companions.
